What will happen if I start a game verified by the hash of block?

[BenCodie]

You wouldn't be the first to do this. The problem with it is the time that it takes for a block to be mined. People want instantaneous betting which is why historically, games using this form of superior fairness still have not survived.

If you are able to allow unlimited, instant bets and have all bets verified by the block hash, while producing different, verifiable results, then you may just be onto a winning idea. Otherwise, a platform where the block hash used for result fairness with limited bets per minute, may fall behind just like predecessors with the same concept.

Good luck!

First of all, we must have a domain name, such as stareatme.com. Do you think this domain name is okay?

I think you should think of another name. stareatme can be read as stare at me as it can be read as star eat me! Besides it's very expensive, it costs almost $4k. And mist importantly, it doesn't give the impression it's for a gambling website.
But before thinking of the domain name, you should focus on the concept of the game itself because this is what matters the most.
Using block hashes to determine game results is not something new but all those who did it switched to other more effective methods.
